iMac (PM61) quieter fan?

iMac (PM61) quieter fan?

I'm running Ubuntu 12.04 on my iMac G4 1GHz (PowerMac6,1) and I've been looking for any installable option to quiet the fan, nothing I've found mentions PowerMac6,1 and the modules installed don't even mention different PM models, just therm_windtunnel.ko & windfarm_core.ko - this first module won't load (No such device) and the second isn't used by anything (yet), do I need to install a .deb package that'll talk to this module?

I know this is not really about development but it's specific to PPC, ok? :-)

Oh, I also have a Dual 2.0 GHz G5 (PowerMac7,3) that I'm keen to get Ubuntu running on as a headless server and it'll need fan controls too. What I mean to say is, I'm keen to help out with these two pieces of hardware should you need testers for them specifically.

I don't know much about the fan control on the iMac G4. You can try
sending me a dump of /proc/device-tree (a tarball), it might tell us
more about what's in there.

This should be fully supported already.

Cheers,
Ben.
